It's also interesting that this system is headed towards Earth at an angle of roughly 45 deg.

In as little as about 27,750 years, it will be only 3.2 lyrs away and will be about 80% brighter, possibly becoming the 2nd brightest "star".

[Nit on article: "Alpha Centauri A, also known as Rigel Kentaurus, is a yellow star of the same type (G2) as the sun..." * Caugh* This (today) only refers to its spectral type as used, for instance, in the H-R diagram. If seen visually, with attenuation, it will have no hint of yellow, as is true of the Sun. ]
